However, it seems that he isn't wanted back.
According to Bleacher Report's own Damon Martin, sources within Team Jackson-Winkeljohn claim that Guillard is not welcome to rejoin the New Mexico camp, refuting earlier statements made by Guillard on his Twitter account.
Overall, the story turned around in just a day, as summed up in the following tweets:
Im no longer a blackzillian I went back to where I belong Jackson's:-):-):-):-):-) — Melvin Guillard (@Young__Assassin) March 24, 2013
I'm hoping to find out more later but I've been told specifically by sources that Melvin Guillard will NOT be back at Jackson's MMA — Damon Martin (@DamonMartin) March 25, 2013
Sherdog also corroborated the report with "a source close to the situation" stating that Guillard "will not be granted access to train" with the team at Greg Jackson's MMA.
Moreover, whoever runs the official Twitter profile for the camp is taking the same stance, reposting Sherdog's story on their main feed.
Guillard has not since updated his Twitter profile.
Additionally, he may continue to remain silent due to a recent MMA Junkie report regarding his two outstanding assault charges and three misdemeanor charges in New Mexico—not to mention this tidbit regarding his relationship with his old team:
"The Young Assassin" had angered the team in interviews he gave about a move this past year to Florida's "Blackzilians" team, a source close to the MMA team told MMA Junkie.
"He's not allowed back here," said the source, who asked for anonymity given the sensitive nature of the talks and the team's history with the fighter.
Everything said so far flies in direct conflict with prior statements that Guillard made previously made about his split with the camp.
During a January 2012 interview with MMA Weekly, Guillard stated that his move to the Blackzilians' camp in Florida was fueled by a desire to improve his skills and not any personal grudge.
That much appeared to be true even when Guillard faced his friend Cerrone at UFC 150, losing a one-round war that resulted in a "Fight of the Night" bonus for both men along with an extra "Knockout of the Night" bonus for Cerrone.
Although Guillard and Cerrone were very friendly before, during and after their match, that apparently didn't represent the scope of his relationship with the rest of the Greg Jackson's MMA team. But at the moment, Guillard currently finds himself without a training camp to call home.
